e272ae281f task: Introduce gst_task_resume() API
This new API allow resuming a task if it was paused, while leaving it to
stopped stated if it was stopped or not started yet. This new API can be
useful for callback driver workflow, where you basically want to pause and
resume the task when buffers are notified while avoiding the race with a
gst_task_stop() coming from another thread.

09141c6e1f Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

8983cce9f6 gst: GST_EXPORT -> GST_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

92d3246f76 gst: mark symbols explicitly for export with GST_EXPORT
One omission: gst_allocator_sysmem_get_type() was
exported but never in any public header file.

b2aa56f4e3 task: add separate methods to add enter/leave callback
Remove the structure of callbacks and replace with separate methods to register
each callback. This is much more binding friendly.
